I have a couple of fresh water well-planted tank and about 10 months ago, I started a shrimp only tank just for the fun of breeding them. That was my first attempt at shrimp so after alot of reading, I decided to play safe [for now] and start with Red Cherry Shrimp.
These shrimp are supposed to breed like crazy from what I've read on the internet.. No one seems to have problem with them AT ALL.
Guess what ? In 10 months, NONE of my shrimp got babys.. Not even eggs in there belly, nothing.
Since then I've tried ALOT of different things but nothing has worked.
One of the problem that might be the source, is the high pH in the tank. My tap water is a flat pH of 7.0. I have a a electronic pH meter and I double-check it from time to time with a pH test also.
I have no idea why, but after 24h of a water change, the pH always raise to 8.0-8.1. I have 6 other tank and all the other tank are stable at 7.4-7.6 so it's not my water.
I was about to try Seachem Acid Buffer/Alkaline Buffer but I'm a little bit worry about that espacially because quantity will be an issue with only 5gallon so I decided to post here see what you guys think about it.
Here are all the infos that might be usefull to help me:
Shrimp: 12 red cherry shrimp (they are not the original from when I started the tank)
Tank: 5 gallons
Age: 11 months
GH: 3.36 (60mg/L)
KH: 2.24 (40mg/L)
Tap water pH: 7.0
Filtration: foam, CupriSorb*, Purigen, Matrix (not MatrixCarbon)
Filter: AquaClear 20 (at about 66% speed)
Substrate: Seachem Flourite Black (I changed to that about 3 weeks ago because the girl at my LFS told me that the white crushed rock I was using as a substrate might raise the pH.. but it didn't help and I don't know if you've ever changed the substrate in a planted tank but.. anyway
* I added CupriSorb about 2 month ago because I moved to an new "old" house with cooper pipe about 3 months ago and I tested the water and I had 0.1ppm of cooper in it. I don't think it's enough to hurt the shrimp but hey.. I have nothing else to test
- I do my weekly 20-30% water change
- I use Aqua-Plus Water Conditioner (I've also tried Seachem Prime but it's too concentred to mesure corretly for a 5g)
- I give my shrimp some really really small bites of algea waffle every other day that I usually give to my plecos (no, not in this tank) (they usually finish it within 20-30minutes)
Untill last week I was giving this tank 0.4ml twice a week of Florish Excell but I started giving that about 2 months ago thinking it would help my plant but there's not enough light anyway so I stoped that.
Here are some picture of the tank:
This is the side view:
And finally, this one has nothing to do with my problem:
After 10 months to trying about anything I could think of, I'm open to new Idea and I'm also willing to try about anything..
